A kind of die assembly of the Anti-dismantling housing injection demoulding
Technical field
It the utility model is related to a kind of injection mold, and in particular to a kind of set of molds of Anti-dismantling housing injection demoulding Part, belong to injection mold technology.
Background technology
In many injection-moulded housing process, generally require to design side opening to its two sides, its bottom inside edge is designed Overhead kick, for some housings in order to prevent outside dismounting, it can set self-locking structure, and when positive opening housing, it can fracture buckle, Include the feature of all round closure, two avris recess on existing injection molding product with side, it may appear that need synchronous, more The situation of heavy side side core_pulling demoulding, it is difficult that directly it is stripped, in addition, side opening and overhead kick also are difficult to the disposable completion demoulding; Therefore, Chinese Patent Application No.:201620053428.7, disclose a kind of machine box ejection die with barb and side opening, bag Square enclose for including the opening of three sliding blocks formation one sets, and is arranged at the taper pin on the inside of the two opposition sliding block, and the taper pin is close to sliding Block one side offers multiple side top activity caulking grooves;Embedded with side top on the inside of the side top activity caulking groove.It is of the present utility model to have The machine box ejection die of hook and side opening, using three sliding blocks to the surface side hole depanning of machine box three, inner reverse fastener taper pin depanning, pass through Side top prevents product ejection deformation, during taper pin rises, can be formed to barb movement outside and tilt depanning, it is stripped Simply, and casing barb quality can be ensured;But it can not realize the demoulding of buckle slot.
Utility model content
To solve the above problems, the die assembly for being molded the demoulding is used the utility model proposes a kind of Anti-dismantling housing, its The disposable demoulding of buckle slot, side opening and overhead kick can be realized.
The die assembly of the Anti-dismantling housing of the present utility model injection demoulding, including the sliding block that two opposition are set, and set The matched moulds position on sliding block inner face top is placed in, and is arranged at multiple back-off taper pins on the inside of matched moulds position, two sliding block depannings of side opening, Inner reverse fastener taper pin depanning, during taper pin rises, it can be formed to side opening movement outside and tilt depanning;The sliding block A clamp is provided with the inside of matched moulds position;Slide block insert is movably set with the clamp;Slide block insert both sides activity is embedding Conjunction has two right angle sliding blocks;Two right angle sliding blocks form two symmetrical semiclosed STH grooves, and it can be with the flexible T on another housing Type buckle is chimeric to form one, when disassembly is desired, it is necessary to carry out destructive dismounting;It can ensure the original-pack of body;It is described Sliding block outer avris in right angle is fitted on slider guide part;The slider guide part is fixed by sliding block spring and spacing supporting plate; The slide block insert is fixed on demoulding sliding block by pin;The demoulding sliding block both sides are provided with press strip;The demoulding sliding block Latch plate is installed with clamp afterbody;The latch plate activity passes through a power lever;The power lever is connected to the demoulding and slided On block;Force application spring is installed between the latch plate and demoulding sliding block;The force application spring is installed on power lever periphery;It is de- During mould, exerted a force to power lever, drive demoulding sliding block action, demoulding sliding block compacting force application spring, retreat outside core pulling, now, Slide block insert synchronously retreats;Because slide block insert is in the pulling function of embeded slot, right angle sliding block slides along slider guide part;In cunning Under the promotion of block spring, drawn close to center, complete the side core-pulling of product two halves closed side opening slot.
Further, the sliding block is provided with ejector sleeve in back-off taper pin avris.
Further, the clamp periphery is provided with shield.
Further, the right angle sliding block inner face offers T-slot;The slide block insert is chimeric with T-slot activity.
Further, its front end of the slide block insert to rear end is crossed to being wider than from narrow successively.
Compared with prior art, Anti-dismantling housing use of the present utility model is molded the set of molds of the demoulding to the utility model Part, simple in construction, practical, it can realize the disposable demoulding of buckle slot, side opening and overhead kick.
